Linux hard drive benchmark & bottleneck testing software suite for performance
The stress test of hardware (hard drive benchmarks) is a simplistic test. There are a number of benchmarking applications software that can be used as hard disk (storage) stress testing. My favorite is Bonnie++ software.
From the project home page:
Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance. Then you can decide which test is important and decide how to compare different systems after running it. I have no plans to ever have it produce a single number, because I don't think that a single number can be useful when comparing such things.
There are a many different types of file system operations which different applications use to different degrees. Bonnie++ tests some of them and for each test gives a result of the amount of work done per second and the percentage of CPU time this took. For performance results higher numbers are better, for CPU usage lower are better.
It test more than 2Gb of storage on 32-bit machines, and tests for file creat(), stat(), unlink() operations.
Install bonnie++ for Linux hard drive benchmark test
Download from official web site or use apt-get to install bonnie++:
# apt-get install bonnie++
Source code installation
Download source code and compile as follows:
$ cd /tmp
$ wget http://www.coker.com.au/bonnie++/bonnie++-1.03a.tgz
$ tar -zxvf bonnie++-1.03a.tgz
$ cd bonnie++-1.03a
$ ./configure
$ make
# make install
How do I use bonnie++?
Simply type bonnie++ or bonnie:
$ bonnie++
OR
$ bonnie

Caution:This test can put very high load on the disk subsystem make sure you schedule test and inform users.
